"Good networking connectivity is a requirement for a good Dota 2 experience. While we work on the core problem, we’re also working on reducing its effects – this week’s update includes improved detection of Poor Network Conditions. Previously, our detection algorithm was only triggered when multiple players completely lost connection to the game server. This new algorithm will now monitor the actual quality of the server’s connection to its players, and trigger in the case of poor connectivity for multiple players. Matches flagged as having Poor Network Conditions will be immediately safe to leave, and won’t record their results."
